17:24:21<-[S53]: Sct config Heap Base[1100BFFF] size = 27980 (~27KB)

17:24:21<-[S63]: Region Name Base Addr Size (Bytes) Span (Bytes)
17:24:21<-[S63]: ER_ZI 0x110052B4 0 6860
17:24:21<-[S63]: HEAP_KE 0x11006D80 4 21120

请问SDK中os_get_free_heap_size 的大小，是与(uint32_t)&Image$$ER_ZI$$Limit 关联还是 (uint32_t)&Image$$HEAP_KE$$Base 关联？按照打印出来的数据，我的理解是最大不超过21120 ，但是os_get_free_heap_size = 26676 ，是否包含ER_ZI的空间了，还是我的理解有误？
